Loom is a great example of the Java designers still not getting it. Taking on a lot of JVM complexity in order to reuse the same broken API.

Not breaking APIs is pretty considerate of your users.

Agreed. But it can also mean not actually achieving at all what you set out to do. I don't know if that is the case for Loom specifically, but that seems to be what was implied by the parent comment.
